[PATCH] pinctrl: meson: amlogic-a4: use nolock get range

[Xianwei Zhao via B4 Relay]

From: Xianwei Zhao <xianwei.zhao at amlogic.com>

Use pinctrl_find_gpio_range_from_pin_nolock() instead of
pinctrl_find_gpio_range_from_pin() when configuring a pin or
setting a GPIO value.

This avoids taking the lock and allows the code to be safely
called from interrupt context.
